Achilles is an evolution simulation based on Larry Yaeger's PolyWorld. It uses Hebbian neural networks, and an extremely simplified physical model that allows virtual organisms to interact freely in a simulated environment.

Achilles was designed and compiled originally on Linux, but it is completely composed of portable C++ code and uses only portable libs such as SDL and OpenGL, therefore it should be trivial to port. All that is needed is hardware to compile on. Any porting efforts that are in progress or successful are welcome to contribute patches back to the main source tree.

What do the colors mean?The organism colors:The brighter red, the more aggressive The brighter blue, the more likely to mate Yellow indicates `dead' organisms, or sources of food

The organisms are given the color of surrounding organisms as an input to the neural network. This emulates 'vision'.Size is an attribute of the genetic algorithms and thus each organism obtains its dimensions from its parents.

Requirements:

· an OpenGL implementation· GLU and GLUT· Simple Directmedia Layer

What's New in This Release:

· Did away with silly version numbers and opted for a single digit.· Fixed Debian/alpha build by replacing 'unsigned int' with 'png_size_t' in screenshot.cc
